Domande Frequenti

Cos'è Base64 codifica?

Base64 is a binary-to-testo encoding scheme that represents binary data in ASCII stringa formato. It is comunely usod for transmitting data over media designed for testo, such as embedding images in HTML or emIAl attachments.

When should I uso Base64?

uso Base64 when tu need to embed binary data (images, files) in testo-based formatos like JSON, HTML, CSS, XML, or emIAl. It is also usod for basic data obfuscation and API authentication headers.

Base64 comprime i dati?

No, Base64 actually increases data size by approximately 33%. It codificares 3 bytes of data into 4 ASCII characters. uso compression before Base64 if file size matters.
